Business Applications: ERP, CRM, SCM and Enterprise Systems

What the exam tests

This domain tests integrated enterprise applications, their modules, process flows and implementation risks. Expect ERP, CRM, SCM, master data, business process reengineering and order-to-cash examples.

Core rules and concepts

  • ERP integrates core modules such as finance, procurement, manufacturing, sales, inventory and HR around a common database and process model. Benefits include single source of truth and process discipline; risks include costly customisation and upgrade difficulty.
  • CRM has operational, analytical and collaborative dimensions. Operational CRM supports sales and service; analytical CRM segments and predicts; collaborative CRM connects channels and partners.
  • SCM covers plan, source, make, deliver and return. It improves visibility and reduces the bullwhip effect; supplier relationship management is a related area.
  • Enterprise systems impose process discipline, so business process reengineering and master data governance usually precede or accompany implementation.
  • Success depends on executive sponsorship, data quality, user adoption and realistic scope.

Worked example

A customer order enters CRM. ERP checks credit and inventory, warehouse fulfils, finance invoices, and the general ledger posts revenue. Each module updates shared master data. Reasoning: the value is an integrated order-to-cash flow with one customer and product definition. If CRM is a separate silo, staff reconcile orders manually and duplicate data. The exam rewards naming the process flow, not just listing modules.

Traps that cost marks

ERP is not just finance software. Heavy customisation raises future upgrade cost and reduces standard-process benefits. CRM is not a contact database; it is a customer process capability. SCM is broader than transport and warehousing. Ignoring change management and data quality causes failure.

Key points

  • ERP integrates core processes through a common database.
  • CRM spans operational, analytical and collaborative capabilities.
  • SCM coordinates plan, source, make, deliver and return.
  • Master data governance is critical for integration.
  • Customisation and weak adoption are major ERP risks.
